  2. Communication Engine : Over View TCPServer TCP Listener Msg RCV MsgQueue Register CommEngine Send Msg API

  3. Communication Engine • TCP Sever : Demon always running • TCP port (4444) Listening • Process • A node try connect -> accept->receive msg ->Queuing Message • Message Queue handling • Socket Interface • Receive message • Send message

  4. Class TCP Server • Thread Have to wait until accept a connection… • Message Queue Using HashTable (id = key, msg = value) Synchronization ( Mutex or Monitor)

  5. Class CommEgine public bool SubscribeMsg(byte[] id) - insert id in the register public bool UnsubscribeMsg(byte[] id) - delete id in the register public byte[] GetMsg(byte[] id) - register check -> get Msg from Msg Queue -> return Msg public bool SendMsg(byte[] id, byte[] msg, string ip) - create a socket -> connect -> send Msg
